Justed tested a new game and the missions generated are:
alienMissions:

region: STR_NORTH_AFRICA
race: STR_FLOATER

So I don't think there r any conflicts going on I was just silly shooting everything, well almost everything. I assume that another alien base mission will eventually happen in my current game, April's missions look interesting incl Ethereals:

These are from midnight just into April 1st.
Good so you got the Mission
Ethereals should not show up in April!
They are supposed to show up ingame in the beginning of August. I just doublechecked my Ruleset and however you get those ethereals, i have no clue. YOU definitly should not have them.
And Retaliation Missions should be triggered from the UFO's you shot down.
I will ask one of the developers later if there is a case were Retaliation Race can be from another UFO.
I can only presume that one of your other Mods interferes with this, but i have no clue so far.
In my testgame i didn't had Ethereals so far, and all other Races were appearing in the correct order.
It is possible that for some odd reasons, the game defaults to XCom1Ruleset, but even then you should not get Ethereals in April (which is your 4th Month were you get snakeman on mass).
